Effects of Fluid-Structure Interaction on Dynamic Response of High-Rise Intake Towers
Publication: Earth and Space 2016: Engineering for Extreme Environments
ABSTRACT
Intake towers as the entrance of spillway or diversion system constitute the most common structural configuration in large water conservancy and hydropower engineering. The safety and functional capability of intake towers in the event of a major earthquake are crucial, since the controlled release of the reservoir could help to prevent catastrophic failure of a dam after an earthquake by reducing the hydrostatic loads. Therefore, the seismic capacity of intake towers is a key technical issue. In this paper, giving proper consideration to the dynamic interactions of the main tower with the hoist chamber, reservoir, and foundation effects of the fluid-structure interaction on dynamic responses of intake towers and seismic whiplash effects of hoist chambers were studied. Based on a practical project, potential-based fluid elements were employed to analysis and investigate the effects of the reservoir compressibility on natural vibration characteristics of the integral structure, hydrodynamic pressure, and seismic responses of the main tower and hoist chamber.
